I used some of these terms in my last video so I am including them here. Anything that touches your photos should be acid-free and lignin-free, including paper, glue, markers and stickers. If not, your photos will discolor and disintegrate more quickly than they would naturally. Products that are photo-safe will be labeled as such.
Acid Free: Many papers can be considered acid free immediately after manufacture however unless they have been treated with a neutralizing agent, chemical reactions will cause the paper to become acidic over time. Acid causes paper and photos to disintegrate. This aging process is slowed significantly when acid is removed from paper during the manufacturing process.
Lignin Free: Lignin is the natural bonding element which holds wood fibers together. Newsprint contains lignin—you’ll notice how brittle and yellowed a newspaper becomes after just a few days. Like acid, lignin can be removed during processing to make scrapbooking paper safe.
Crop: Cropping is the trimming of a photo to remove unnecessary sections. Cropping should be done to improve a photo. Cropping also allows for more photos to be added to a page.
